Condensation or moisture on the exterior of the refrigerator cabinet or around door seals.

Safety: Unplug the refrigerator before inspecting electrical heaters.

• Reduce door openings: Minimize how often and how long doors are left open, especially in humid weather.
• Inspect gaskets: Replace damaged or hardened door gaskets with Grundig-compatible seals.
• Check installation: Ensure the fridge is not installed in a very damp area without ventilation.
• Frame heater check (if equipped): Some models have a heater around the door frame. If condensation is heavy around the frame, the heater circuit may have failed and should be checked by a technician.
